This invention relates to improvements in switch buttons and more particularly to buttons ofthe character which are used in con- 1 trated in Fig. 1 my improved switch button nection with rotary snap switches.

An object of applicants invention is the production of a switch button which may be quickly assembled and attached to the stem of a rotary snap switch'thereby eflecting a great savlng in tune.

Another object of applicants invention is 5 the production of a button for a rotary snap switch which will resiliently secure the cover for the movable parts in place.

Another object of applicants invention is the production of a constructionwhich will permit the use for switch buttons of materials, such as porcelain and others in which metals are not readily molded or cast.

A further object of applic'ants invention is the provision of a switch button of the above type including in its construction,

preferably a non-conductive body having a bore and sleeve ,positloned w1th1n the bore with a coil spring surrounding the same together with improved means seated within the outer open end of the bore cooperating with the sleeve whereby to restrain displace ment of the sleeve.

A further object of applicants invention is the production ofa switch button of low cost, durable, of a small number of parts and highly satisfactory for itsintended purpose.

Many other objectsand advantages of the construction herein shown and described will" be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combiclaimsL characters indicate like or corresponding.

In the drawings, wherein like reference parts Fig; 1 is an end elevation of the device applied to a rotary type of electrical switch 2 is an 'endelevation of the switch button Fig. 3 is a vertical secticn of thes'ame; and

to the drawing, I have il1usapplied to a snap switch generally indicated] by the reference character 1. At 1, is shown a cover for the inner parts of the switch. ,At-Q isshownmy improved switch button whichispreferably "formed with wings 3. However same'may be of any suitable contour such as round, oblong, etc. The switch u button 2 is formed ofa base 4 with, a bore 5 therein; The bore 5 maybe ofany contour such that the head 6 on the sleeve/7 is constrained to rotate therewith. However,

same may move longitudinally in and out of J bore 5. The term sleeve is here usedto include a solid or partially solid construction.

The sleeve 7 except-for the head 6, is of small r diameter than the'bore 5 which provides space for the accommodation of a spring 8 which clips over the sleeve 7 and engages. the head thereof. The outer end of bore 5 is preferably enlarged as shown'at 18. In the enlarged portion is positioned a combined sleeve supporting spring retaining member 9 which preferably engages the shoulder 10. Thus, holding the sleeve 7 inf place. and maintaining preferably a slight tension on thespring 8." The member 9 is preferably disc-shaped and has an annular groove 11 in. its periphery which is positioned opposite the annular; groove 12 on the incombined sleeve supporting spring retaining member 9 is held in the bore 18. by means of the-resilient member J13 which is so formed that same will spring outward into the groove 12 and still be engaged by the groove 11. It is thus seen that the head 6 ofthe nerwall of the enlargedaportion 18. The .7

sleeve 7 is resiliently urged into the bore 5;

the end thereofwhich accommodates a stein 15. -The1nember13 is shownin position in Fig. 4; It is thus seen that a highly eflicient The sleeve 7 mayhave an internal bore 14: in 1 device is provided satisfactory for its in? tended purpose.
